'- RECEPTACLE WIRE-LOCK.

To all whom it may concern Be -it known that I, \VITTER W. O. FEN- ETY,subject of the King of Great Britain, residing at Fredericton, in theProvince of New Brunswick and Dominion of Canada, have invented certainnew and useful Improvements in Receptacle VVire-Locks, of which thefollowing is a specification, reference being bad therein to theaccompanying drawing.

This invention relates to improvements in receptacle wi re locks, andhas for its object the provision of an inexpensive, practical andefficient attachment, capable of use, for example, in connection with anelectric lamp, for securing the latter to and in electricalcommunication with the usual insulated line wires.

While, as suggested, for the purpose of an adequate disclosure of theinvention, I

proved details and relations of parts will be apparent.

In the drawings: Figure l is an elevation of an electric lamp and itssocket provided with my improved device coupling the same to line wires;Fig. 2 is a cross sectional view on the line 2-2 of Fig. 1, looking inthe direction of the arrow; Fig. 3 is a vertical sectional View showingthe device as applied to the wire; and Fig. 4 is a transverse sectionalview through the device and wire.

Referring more particularly to the drawings wherein like referenceletters designate corresponding parts in the several .views, Arepresents an ordinary incandescent electric light bulb and B the socketto which the bulb is detachably secured, in the customary manner, thebody of the socket member being of insulating material and having anoutwardly projectingflange C.

refer to the s )ecific use thereof in con1b nre -T.0.eosite ortio'n's ofthis base flan 'e m l a t z: y

tion with an electriclamp'whfie the socket would carry the securingmeans referred to,

it will be apparent to persons skilled in the art that other devices orimplements, which I have generally termed a receptacle, may be coupledto the wiring.

It is recognized that either for temporary or emergent use,'it isdesirable to tap a line wire at some convenient point to utilize theelectrical energy transmitted therethrough, and with this in mind, thepreferred embodiment of my invention embraces a securing device, which,as an incident to locking the device on the wire will simultaneously cutinto the insulation of the wire to effect electrical contact between thedevices and wire and in turn through the lamp or other implement ordevice carried by the receptacle to which the improved securing meansare attached.

I More specifically the invention compreadapted to assume aninterlocking relation when the parts are forced together with the linewire therewithin.

In the accompanying drawings forming part hereof, I have illustrated thebefore mentioned preferred embodiment of the in-' vention and from thesedrawings, when considered in connection with the specific descriptionhereinafter contained, the im- 'G. The upper member of the device isrepresented at H, and at the opposite edges 'thereof,-the same carriesintegrally downwardly bent flanges J, sharpened at their edges j, toconstitute cutters adapted to sever the insulation of the wire ineffecting contact with the metal strands on the interior of theinsulation in securing electrical communication between the device andsaid metal strands.

-The device is adapted to be forced together .by a pair of pliers or the.like, to cause the knife edges to penetrate the insulation and securethe electrical contact referred to when any resiliency of the parts willbe overcome, and said parts locked in position by means of a catch Kcarried at the free end of the upper portion H of the device adapted topass through a slot 6. i the securing or lower member E, the catch beingadapted to engage the under surface of the member E bordering the slot,as will be readily understood.

It will not be necessary herein to define lamp.

specifically the lines of current transmission through the lamp socketand lamp, these being diagrammatically represented in the drawings andit being obvious that the base or securing portions of my connectingdevices are in electrical communication with opposite terminals leadingto and from th From the foregoing construction, it will be apparent thatin a simple and efiective manner I have provideda device enabling thefastening of any type of receptacle to a wire, useful in manyconnections, but especlally 1n the servlce herein specifically outlined,namely the securing of an electric lamp to line wires at any accessibleportion of the wiring, and as an incident to the fastoning of the devicein place and the obtaining of electrical communication between the lampand the wiring.

While I have herein disclosed a special embodiment of the invention, itwill be clear I I to persons skilled in the art that said invention iscapable of embodiment in other forms and devices as may be embracedwithin the scope of the hereto appended claims.

Havin thus described the invention,

7 what is c aimed is:

1. ,,A device of the character described "composed. of sheet metal bentto f orm a securing-v part having awire seat, an opfiisite, part bearinga cutter for insulation adapted part bearing a cutter for insulationadapted to sever said insulation when the parts are forced together,said cutter edge being an integrally offset portion of the opposite partand means for locking the parts in closed position including a latchcarried by one of the parts adapted to 'interfit with a complementalportion of the opposite part.

8. A device ,of the character described comprising a securing portionadapted to be connected to a socket and having a wire seat and a contactportion bearing a knife edge opposite to said seat and adapted to beswung toward theseat for placing the contact portion in engagement withthe wire, and cooperating latching. means carried by said parts forsecuring the swinging contact portion in a closed position.

4. A device of the character described,

- comprising a member having a part for connection with a socket,another complemental member secured at one end portion to said first-mentioned member in a manner enabling the same to be forcibly swungtoward the latter, one of said members being formed to provide a seat ofa size to receive an insulated wire, and one of said members carrying acontact portion relatively fixed thereto to cut the insulation andeffect elec- .In testimony whereof I hereunto afiix my :Signature in thepresence of two witnesses.
